How much methadone to take with no tolerance

[Opidopecake]

Hello.
I have searched and searched for a question like this but I couldn't find anything that I could compare to at all.
The user is a male, no opiate tolerance whatsoever. He is very tall and about 200 lbs. He wants to try methadone for the hell of it, Wondering what a good dose to start out as. I was planning on titrating the dose...
would 20mg be good to start and titrate from there. He doesn't want to be retarded he just wants to feel really good. Euphoria an stuff.
If this is already posted somewhere else i apologize in advance.
Thanks !

If you have no tolerance to opiates, you could start at 10 mg if you really want to try methadone. It's not very euphoric though.

10mg should get you nodding (and I found methadone pretty euphoric). 5mg will be more like threshold effects. Don't take more than 10mg at once the first time, and don't redose within 24 hours, methadone has a very long half life and people have died by redosing, even with an Rx.

As FM said,

Start at 10mg, don't re-dose within a 24 hour period. It's got a ~22 hour long half life.
